ADJUSTABLE TIP FOR CANES AND THE LIKE.

Application filed November 3, 1924.

To a7] willem t 77mg/ conce/'11...'

Be it known that I, CHARLES SIFFERLEN, a citizen of the United States, and a residei'it of Joliet, in the county of IVill and Siate of Illinois, have invented a new and useful Improvement in Adjustable Tips for Canes and the like, of which the following is a full, clear, and exact description.

My invention relates to improvements in adjustable cane tips, and it consists in the combinations, constructions, and arrangements herein described and claimed.

The use of resilient tips for canes and crutches has been somewhat retarded because of the fact that these tips tend to wear away quite rapidly, and this necessitates their frequent replacement.

An object of my invention is to provide a resilient tip which obviates the necessity of frequent replacement.

A further object of my invention is to provide a device in which a relatively7 small portion of the resilient tip is exposed at any one time, means being provided to permit the exposure of more of the tip as the end thereof wears.

A further object of my invention is to provide a resilient tip for a cane or the like which has the major portion thereof protected, the protecting member being instantly removable to uncover as much of the tip as is desired.

Other objects and advantages will appear .in the following specification, and the novel features of the invention will be particularly pointed out in the appended claims.

My invention is illustrated in the accompanying drawings forming part of this application, in which- Figure l is a side elevation of the device,

Figure 2 is a sectional View through a portion of a cane constructed according to my invention, and

Figure 3 is a section along the line 3 3 of Figure 2.

In the drawings, 1 indicates the body portion of a cane, crutch, or similar article, which has a reduced portion 2 at the lower end thereof. Enclosing the reduced portion 2 is a metal sleeve 3 which is of a thickness to bring the outer surface of the sleeve substantially flush with the outer surface of the body portion l. The sleeve Serial Nb. 747,637.

3 is threaded externally, and, as will be observed, extends substantially to the bottom of the reduced portion 2. The lower which is further secured by means of screwsl ll. The shield 8, as'will be observed, overlies the sleeve 7.

From the foregoing description of the various parts of the device, the operation thereof may be readily understood. Normally, a portion of the rubber tip 5 is exposed, as shown in Figure l. The movable portion of the tip is protected and re-enforced by the sleeve 7. lVhen, however, the exposed portion of the latter wears down to a point where the lower end of the sleeve comes in contact with the ground, then the sleeve 7 may be shifted by screwing it farther up on the sleeve 3. The shield 8 overlies the sleeve 7 far enough to prevent mud, dirt, or water from reaching the threads on the exterior of the sleeve 3, so that the sleeve 7 may be readily screwed up when it is desired to expose more of the tip.

IVhile I have described the device as being particularly applicable to canes, it will be apparent that it might be used for crutches, chair legs, or other similar devices without departing in the least from the spirit and scope of the invention.

I claim:

l. An adjustable tip construction for canes and the like, comprising a resilient tip member, means for securing said tip member to the bottom of the body portion ot' the cane, an externally threaded sleeve carried by said body portion, an internal- 1y threaded sleeve surrounding said tip and engaging the threaded sleeve on the body portion, said internally threaded sleeve being adjustable relative to the first named sleeve to expose more or less of thetip. as desired, and a cylindrical shield secured at its top to said body portion and arranged lo extend over the upper end ol said adj uitab'le" sleeve;

2. Air

cane, said sleeve being threaded exteriorly,

a resilient tip secured-to. the lower end ofi said sleeve, an internally threaded sleeve surrounding said tip4 andv engaging said adjuslahle tip conrrrietionforcanes and the like Comprising a metal. sleeve surrounding the@ lower endl of. the

exei'ierly threaded sleever` said internally 10 arranged to extend over the upper end of 15 CHLES SIFFERLEN.
